I Don't Want X1

The cable TV box xfinity gave me a few months ago stopped delivering Video On Demand a few days ago. They want me to replace it (for free) with a new box that will deliver VOD but is controlled by the X1 user interface, which I find unusable. Does anyone know a solution perhaps using a cable box from another supplier that does not use X1? Xfinity customer service and technical support people haven't been helpful. They reset my existing box repeatedly, which accomplishes nothing.

Here's their announcement-- https://www.xfinity.com/support/articles/xfinity-removed-select-tv-boxes
